QUICK CHANGE WEB SPLIGING- DEVICE Applicationled April 10, 1930, SerialNou-143,083. Renewed July 29, I19353.

This invention relates to the art, of splicing webs inthe printing ofnewspapers and in other machines which require rapid operation. 5 Theprincipal objects of this invention are to provide limproved practicalmeans for sup-l vide means whereby the pressure of the web,v

against the new roll is applied through and around the tension straps,thereby eliminating the necessity of lifting 'the brush out of the waybefore bringing-the new roll into 0 operating position against thetension belts and providing more space for installing and operating thebrush mechanism 1n cases Where this invention is used in connection witha machine'embodying a brush mecha-v nism for holding Vdown the webagainst the new roll at the instant the pasted portion of the new rollengages the expiring web and to provide means for severing the webw1thout undue disturbance.

:o Other objects and advantages of the invention will appearhereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 isan end view of a reel for web rolls and mechanism for speeding up. thefresh roll and connecting its end with the expiring web' Fig. 2 is asimilarview of auportion of the same on a larger scale showing the partsin o a different position; g v

A main shaft 6 receives power from a shaft ofthe press and consequentlyruns in proportion to the operation of the press. This shaft by bevelgears 7 and8 operates a horizontal shaft 9 mounted on the frame of aprinting machine. The shaft 9 carries pivoted on it a caterpillar arm10, the free endof which` carries a double ended belt-carrying frame inthe form of two arms 4 and 5. Thisframe is pivoted on a hollow stud 3 atthe end of the arm 10. Itis driven through a sprocket 11, chain 12passing over idlers -14 and sprocket 13. The sprocket 13 is secured orattached to a pulley 15 which in turn carries a sprocket 16 on its otherend. These three elements preferably are in` one piece. A chain 17 runsover the sprockets 16 and 18, the latter being attached to a pulley19.,This provides two points of drive for a belt 20 which is adjustable onthe arm for ta g 80 up the slack. The speed of this belt 20 isproportional to the speed of the press and the parts are so designedthat on contacting with the incoming roll of paper 22, this roll will bebrought up to web speed preparatory z` to the splicing operation. Twosuch caterpillars are pivoted on the shaft 9 and either of them can beadjusted along this shaft to accommodate .paper rolls of dlfferentwidths ofpa er. V

Thegeaterpillar itself shown -herein is also illustrated and claimedinthe prior application of Isidor Tomber Serial No. 264,248, filed-March23, 1928. T e raising 'and lowdifferently however. A motor 38' isconnectedl by a pinion 37 on its shaft and a gear 36 to drive a shaft 33at reduced speed. The shaft 33 is mounted in bearings 34 and is provided-with a worm 32. This worm runs a 100 v2 l 1,591,965 Y segmental wormgear 31. The motor is designed to rotate forward and back in accordancewith the control circuit of the motor shown on the diagramFig. 9 so asto run along enough only to turn the segment through the desired arc.This segment is provided with a curved slot which operates a roll 29 onan arm 28 fixed on a shaft 27. Also fixed on this'shaft is an arm 26which is connected by a link 23 with alpin or stud 24 on the caterpillararm 10. for raising andI lowering it.

The cooperation of the roller 29 with the lend of the slot 30 in thesegment 31 lifts the caterpillar arm 10, when the segment is noved inthe right hand direction. Movement of the segment-.in the left handdirection allows the `caterpillars tos descend until the weight issupported by the paper roll, at which time the arm 28 and roll 29 stop,further motion-of the segment 31 being allowed l 'by the slot 30. `Limitswitches 39 and 40 are provided to stop the segment at its twoextreines.These are connected in the control circuit of a motor 38 as will be seenon the wiring diagram.

The fresh roll 22, as well as the running roll 223,'and the spare roll-at times (not shown) are mounted on a reel 4l supported by a shaft 42.1 This reel is run by a motor 43,

. shown' only in the wiring diagram, by any of the usual connections.Thelsevering of the web just subsequent'to pastlng 1s accom'- plished bya brake 44, the details of which and are held yieldingly by weights 48so as to apply pressure to the web as it passes off the running orexhausted roll.v The removal or addition of some of the weights providesfor varying thextension on the web.

` The shaft 46 isgprovided ,with a weighted arm 50 and also with twoarms 57 near the ends carrying a shaft 68. The arms 57 and a l doublearm or frame 52 at the centeriare, l keyed to the shaft68." At thebottom the arms 51 and 52 are provided with four exten'- -sions 53pivoted to them by knee joints 54,'

so that they can swing inwardly toward the running web roll `bygravit-y, but cannot swing backwardly'past the straight line positionshown in Fig. 1. -It will be seen that4 the weighted arm 50 holds thisstructure against the straps 49 which are directly in engagement withthe four extensions 53 and l are backed up by them against the runningroll 22aL to apply yielding tension thereto. These extensions lengthenout the frame 51, 52, 57 without projecting out and taking up excessivespace when in operative or inoperative position. 'The several arms 51,52 and 57 are held together to constitute a frame by the shaft 68 androds 56 connected across the whole series.

0n the frame of the machine is pivoted an operating handle 59. This isprovided with a spring-pressed detent 60 connected by a link 61 with alever 62'which can be depressed by grasping it and holding. it towardthe handle to remove thc detent from one of two notches 63 in astationary segment 64 fixed on the frame, so that thishandle can be heldin either one of two positions as indicated in Fig. 7. f

The handle 59 is mounted on a shaft 65v which has another arm 66 free onit and oonhected by a link 67 with a stud on the frame madebup of thearms 51, 52 and 57. rlhere is another arm 69 keyed to the shaft 65having a projection engaging the arm 66 or a projection thereon whichmoves this arm and the frame. Consequently the operation of this handlefrom one position tothe other will swing this frame as indicated also inFig. 7. lfVhen this frame is brought'back as shown in dotted lines theextensions 53 bend downl only by gravity, and swing clearc` of thetension straps, but when it is brought down to the full line positionshown in that figure,

they bear on the roll 22athrough the tension Jstraps 49. u 'f' Duringthe ordinary running of the web, the parts are in the position shown indotted lines and are brought down to the full line position only when apaste'r is about to be made. i

It may be remarked at this point that there are two limit switches 70and'71, the purpose of which will be described-later, which are locatedin stationary position with their switch arms movable by contacttherewith by the operating handle 59. When the handle is in itsright-hand position the switch 7() is opened by it and when the handleis in its'left-hand position the switch 71 is closed by it. 1

In the operation of this paster it is desirable to bring the incomingroll 22 up to withinl a predetermined distance from the web W beuforestarting the pasting mechanism. The position at which the reel stops isdetermined by a switch 55. fThe. tripping of this switch is accomplishedthrough a switch arm 91 being engaged by the oncoming roll 22.v

Thisswitch arm is secured to a rod 88 which is mounted free to oscillatein arms 51, 52 and 57. e

On the frame consisting of the arms 51, 52 and 57 are located a-` pairof electro-magnets 7'3, the plungers 74 of which are provided solenoidplungers down when the solenoids are not energized. When they areenergized they pull up the shaft 76 which is mounted to extend acrossthe frame on two bell-cranks 79. On these bell-cranks is a channel iron80 are disconnected.

which constitutes a'support for a brush 81. This iron 80 is providedwith U-shaped offset portions 89 which provide recesses to receive thearms 51 and 52 when the frame is swung forward. `The-brush 81 is made insections to pass between the 'arms 51, 52 and 57. Obviously when the'solenoids are operated this shaft is forced over into pasting positionand drawn back when the solenids The springs, together with the brushbristles, provide for yieldingly forcing the web against the incomingroll.

The arm 52 also carries another solenoid 82 the plunger 83 of which isconnected by a link 84 with a pair of bell-cranks85 and 86. f Whenoperating with a full width web the other arm of this bell-crank 86engages between two collars 87 fixed on the shiftable and oscillatablerod 88 and a spring 90 holds the plunger down normally and normallypushes the rod 88 to the left. The switch arm 91 is located near the endof the fresh roll 22 and this movement of the rod 88 to the left movesthis switch arm 91 beyond the end of the roll. and of the web path whereit will be out ofthe way.

I have shown another switch arm 92 on the same rod 88 which is usedinstead of the switch arm 91 when a web roll of fractional width isbeing used on the right hand side 0f the press.v In this case the righthand collar 87 is loosened and slipped along`the rod 88 up against theother bell-crank 85 to cooperv ate with it in conjunction with another`collar time and one of the bell-cranks 85 or 86 93. In that case theenergization of the solenoid 82 moves the rod orshaft 88 to theright andmoves the switch the end of the web roll. In Fig. 4. one of these switcharms is shown mounted in operativeposition extending' upwa ly from therod 88 and the other in inopera tion extbnding downwardly.

Of course, they are not intended to be used at the same lsalwaysinoperative.

There is a switch 55 which controls the operation of the'solenoid82 andthe closing of this switch not only moves the switch arm out of the waybut also results in the stopping of the rotation of the reel by cuttingout the motor 43 and sets the apparatus ready for making the pastel'.`

It will be understood that the switch arm 91 with the shaft 88 on whichit is mounted is free to oscillate in the bearings of that shaft on theframe made up of the arms 51, 52 and paper roll shaft.

ive posi# 57. On this shaft 88 is secured an arm 96 having a pin 97passing through it. This pin carries a spring 98 backed up by nuts onthe pin 97. The pin passes freely through the arm 96 and is pivotallysecured to a bifurcated arm 99 so that these two arms are pressed towardeach other and toward a pin 100 which is mounted on the frame 52 andprojects from it between these arms. The arm 99 is free to swing on theshaft 88. The action of the spring is such that when there is nopressure on the switch arm 91. or 92 as the case may be, these two arms96 and '99 are held yieldingly against'opposite sides of the pin 100;When the incoming rollA 22 presses against the switch arms and closesthe contacts in the switch 55 that controls the solenoid 82, the latteris deenergized. The spring 90 pulls down the plunger and swings thelevers 85 and 86,v about their respective centers so that the shaft 88,through its collar, is pushed to the left, permitting the switch arm 91to move clear of the web.

The operations of the brush and brake take place in conjunction with thecommutators 102, one of which is fixed to the end of each The brush isbrought against the fresh roll just after the paste has passed thebrush.` y

The wiring diagram (Fig. 9) indicates the' reel as having a selector 116arranged concentrically about its shaft 42 and rotating with it. and ashaving three arms, each one of which is provided with a commutator 102and each with a brake coil 101. In the position shown, the new roll 22has not quite reached the position shown in Fig. 1. and the contactsthere are not completed. The commutator 102 on the upper arm, however.is connected up enough to show how the brush solenoids are brought intoaction and the selector 116 and the commutator on the lower armV to theright are yin position to be connected up by this selector t'o energizethe brake A coil 101. arm 92 beyond The wiring system also involvesthree con- ,rit-actors 107 117 and 124. These numerals are usedindiscriminately to indicate the respective contactors as a whole andthe operating coils shown for energizing them. The contacts operated bythese contactors will be described in detail in connection with theoperation of the machine, but. it is to be noted that two pairs ofcontacts 104 and 111 of the contactor 107 are normally closed and arearranged to be opened when this contactor is energized, While the othertwo contacts 'are opened when it is not energized. In the other twocontactors all the contacts are arranged to close when: the coil isenergized. In the two motor circuits are also shown four additionalcontactors, the operation of which is well understood and will not bereferred to further.

13olv 60 tactor until both the switch 70 and 55 are Operation As therunning roll 22a becomes nearly exhausted 'and it is desirable tooperate the quick change mechanism the reel 41 is substantially in theposition shown in Fig. 1. Thelowering of the lcaterpillar mechanismvwill bring the belt in contact with the fresh web `roll22 and bring itup to web speed. The handle 59, of course, is in its extreme right handposition, holding the limit switch 70 open. Thelatch 60 is released andthe'handle turned to its left hand position as shown in Fig. 1. Thismovement of the handle 59 swings the frame made up of the arms 51, 52and 57 toward the fresh roll and the projection 53 bears against thetension straps and through them against the small expiring web .roll22a. The removal of' the handle 59 from the limit switch 70 causes thatswitchto close its contacts. Also when the handle reaches its' left handposition it closes the contacts in the switch 71. Two

'contacts 104 in the contactor 107 are normally closed. Therefore theclosing of the two switches 70 and 71 will bring the current in from oneof the mains to the other through the switch 71 and contacts 104 to .sthe caterpillar'mechanism is continuously in operation at this time itwill bring the fresh web roll up to speed, suilicient time having beenallowed for this action to take place.

'Whenthe speed of the incoming fresh roll 22 is in synchronism with thatof the web the forward button 108 of the reel moto-r is depressed. Thiscloses a circuit connected with the reel.motor.43 and causes the reel torotate inthe usual `direction until the fresh roll contacts with theswitch arm 91 hereby closing the switch 55. The making of these contactscloses a circuit' to energize the contactor coil 107 Which actionoperates all the contacts of that contactor and breaks the contact at111.` This breaks the reel motor circuit'and causes the reel to stop inthe proper position. It also makes the contact 103 acting as a hold-.infor the coil 107 Aas a conopen. The contacts 113 in this contactor are'also closed at that time which sets the device ready for pasting andthe currentis then connected up to one side of each of the solenoids 73and ready to be connected yon the other side to energize them.

It is necessary that the brush and web be brought against the fresh rollat some point other than that Where the paste is applied. This isaccomplished by putting the paste on in proper relation to the contactsof the commutator '102. The closing of the contactor107 also opens thecontacts 104 thereby deenergizing the solenoid 82.- This action'75causes the rod 88 to be pushed to the left bringing the switch arm 91beyond the end of the roll out of the way of the web.

As the commutator 102 rotates, Va segment 114 thereon makes engagementwith the con- 80 tact 115, which is connected with a line operatingthrough a selector 116 mounted on`v the shaft 42 of the reel. n thismanner the contactor coil 117 is connected up so as to close thecontacts 112, .118 and 119. The. contacts '85 112 being closed togetherat this time, make a hold-in circuit for the coil of the contactor 117.The simultaneous closing of the points 118 causes the solenoids 73 to beenergized. Thus the brush 81 is oscillated against the "99 web andthat'is pressed thereby against the fresh roll 22.

. `While the fresh roll is making a revolution the pasted end, ofcourse, becomes attached to the rpnning web and takes up its coursethrough the press therewith. The energizing of the contactor c`oil 117of courseI closes thecOntacts 119. Thusthe current is completed throughthe contacts 119 to the inner contactsof -the selector 116 to put. pow-100 er on one side of the coil 101 of thebrake 44 and`to' the outercontacts of the selector-116. After almost a complete revolution fromthe time the brush has been drawn in, a contactor segment 122 makesengagement with a con- 105 tact 123 connected with the coil 117Athroughthe selector 116`and also energizing the coil 124 of the other'contactor..v The closing of this contactor closes thecontacts 121 foi`th'e purpose of creating ahold-in' circuit. The 110 closing of thiscontactor also closes the con-4 tacts 125 which, through the selector116 puts the other side of the line in circuit with the brake. In thisway the brake is 'finally set.

The function 'of the selector 116, as is ap- ,115 parent from thewiringdiagram,`\is to select the proper commutator 102 for setting up the.pasting mechanism and `through which pow:- er is supplied for applyingthe brake. The application of the brake. stops the roll 22El 120 and bythe cam action, asset forth in-my last named prior above mentionedapplication, simultaneously passes the knife 45 through the edge of theoldueb. In this way the old web is severedV very effectively without any125 undue disturbance and the actual cycle of pasting is therebycompleted; p

1n order to release the electrical hold-out so that the reelcan be movedinto the tension straps the handle 59 is swung back to 130' its extremeright hand position. This opens both of the switches 70 and 71 andbreaks two circuits completed by them." This action deenergizes allthree solenoids, the 5 brake and the three contactors and permitsforward or reverse operation of the reel.

The raise button 120 of the caterpillar motor is now depressed by handcausing the segment 31 to rotate in a clockwise direction l and lift thecaterpillar mechanism free from the roll 22 which is now feeding paperinto the press. At this point the mechanism. is in the same position' asat the beginning of the cycle and ready for continuing feeding L of theweb and for repetition of the operations which have been described whenthis new roll is about exhausted and the reel brought around to theposition corresponding to that shown in Fig. 1. In that posi- I0 tionthe roll 22 comes into position of the roll 22a and a new roll 22 is inplace ready for the hindle 59 to be turned to the position shown iiiithat gure and for the caterpillar to drop as shown therein. There is areverse button 130 connected up with a reversing circuit for rotatingthe reel backwardly whenever that has to be done, operating, of coursethrough the reel motor 43.

It will be seen therefore that the means for bringing the fresh web rollup to web speed, the bringing of the brush up into position to press theweb against the fresh web roll, the application of the brake to the ex,-piring roll and thesevering of the web are all accomplished throughautomatic means set into operation at different times by the motion ofthe operating handle 59 and the push buttons and that the operation isfurther automatic in that the switch arm, which is operated by the freshroll to start some of these operations, is automatically moved out ofregistration with the web beyond the end of the roll by automatic meansde scribed.

It will also be seen that the pressure of the web -against the fresh webroll is-applied through or between the tension straps, for it is evidentthat the exible bristles of a brush allow its application to the webeven though the bristles be not c ut away in line with Vthe tensionstraps, therebyeliminating the necessity of moving the brush out of theway before bringing the fresh web roll into operating position againstthe tension straps; also that provision is made for bringing the new webinto contact with the old one just after the pasted spot has passed andthus avoiding trouble from that operation. Furthermore, the constructionis such that there is morespace for installing and operating the brushmechanism than has been the case heretofore.

It will be seen that the selector is ployedy to put .the ropercommutator into the circuit for starting up the pasting mechanism andalso the proper commutator to which power is supplied for braking andthat no undue disturbance is created when the old web is severed; Thewhole thing is operated ordinarily by this operating handle and threepush buttons, the fourth button being employed for emergencies when itis desired to reverse.
